Arcana bug rolling gems

i spent more than 11M of silver rolling one gem and didn’t get the one i need, i literally got at least 5 times each of the other spells of arcana but 0 the scratch dealer

the probability of that happening is less than 0.07%, and i did get mysterious stampede 5 times in a row, the thing is that the probability of that happening is abysmal, is arround 0.00007% and thats clearly not RNG

to be honest i really piss off with this, the probability of not getting it after 11M silver is way too low to get this, spending 11M in silver (all my silver) means i dont going to be abble to get my characters to higher item lvl for a while, i really need a refound of silver or something bc this is clearly something bug like
